With heavy rains Thursday — and in the region’s forecast for coming days — the Army Corps of Engineers is warning of the likelihood of renewed flooding in areas where levees remain damaged or open.

The levees south of Omaha sustained about 50 breaches and only some have been patched.

Col. John Hudson, commander of the Omaha District of the corps, talked with state officials along the river on Thursday about the danger.

“It’s important to remember that a significant risk of flooding remains until the federal levee system is fully repaired,” Hudson said. “Significant rainfall will likely lead to higher river stages and increased flow through levee breaches. This will result in flooding in areas where floodwaters had receded.”

In addition to localized rain runoff, the Missouri River will be running higher in the days ahead as a result of increased flows out of the upstream dams. The corps is increasing releases from Gavins Point Dam because of heavy rain runoff above the dam. The agency wants to maintain enough storage room for snowmelt.

Storm puts on a show

Explosive lightning moved through the Omaha metro area Thursday night, along with drenching rains.

The thunderstorm led to the postponement of two games at the Big Ten baseball tournament in Omaha. Additionally, the National Weather Service warned of the potential for flash flooding into Friday morning. Some low-lying roads had already taken on water.
